I recently changed jobs and had the opportunity to interview with several companies. In total, I had on-site interviews with 7 well known tech companies, including Microsoft. Out of those 7, Microsoft's interview process was the absolute worst. I went through their event-based interview process. I was told that I would be interviewed by 4 people, with each person being from a different team, and I would have the opportunity to be recruited by any of those teams. That turned out to be a lie. All 4 of my interviewers were from the same team, and it was a team that I was not interested in joining. I went through the interview anyway, and it was a mess the entire way through. For my first interview, the interviewer was 10 minutes late and didn't even know how to turn on the coding software, so they wasted another 5 minutes trying to figure it out. Eventually, I ended up having to do a screen share and coding in a plain text editor to continue the interview. The coding problem was very easy so I still finished it on time. The second interviewer had a coding problem that was a variation of the first interview, so that was easy to solve. I solved the problem optimally in time and space complexity, but afterwards the interviewer kept telling me to optimize it more. I responded that the solution was already optimal in both time and space, but the interviewer insisted that I over-optimize by short circuiting some loops, even though it wouldn't change the asymptotic running time. I just did what was asked even though it felt like such an odd request. The third interviewer was also late by 5 minutes. Not much else to say here. The fourth interviewer asked me a coding question that I had already solved on Leetcode, so I knew exactly what to do. While I was coding it, the interviewer stopped me and insisted that the way I was doing it wouldn't work. I said that I felt it would work and after some back and forth the interviewer allowed me to continue. Sure enough, I coded it and ran tests through it and it all worked as expected. The interviewer didn't say anything about being wrong. Compared to the other 6 interviews I had, this interview with Microsoft was the worst experience. I won't be bothering to interview with Microsoft again.
